Guitar Fetish pups

GFS pickups: are they okay? I'm looking specifically at a Vintage Hot (http://store.guitarfetish.com/veviexhonibr.html) humbucker, which sounds nice according to their (probably misleading) clips, and the hum-sized (http://store.guitarfetish.com/me90tralp90p.html) p-90 thing, which doesn't have clips. They're both AlNiCo 5s. I don't know a ton about what makes pickups sound the way they do, only whether or not I like how they sound, so anyone with an opinion is welcome and encouraged to share.
